What I'm looking for

I seek a challenging role in a dynamic environment that fosters innovation and growth.

I am a Senior Software Engineer with extensive experience in developing scalable applications and microservices. My journey in technology began with a Master of Science in Engineering from the University of Pennsylvania, where I honed my skills in computer and information technology. Over the years, I have worked with leading companies such as Microsoft, Oracle, and DoorDash, where I have consistently delivered high-performance solutions.

At DoorDash, I developed and deployed an Apache Flink application for processing financial events, which significantly improved the efficiency of our accounting processes. My role at Oracle involved designing distributed backend systems that supported scalable operations, while at Microsoft, I contributed to the development of microservices within the Microsoft Intune suite. I am passionate about leveraging technology to solve complex problems and enhance user experiences.
